Greg NeumayerDisk cache setting is too high?!
by on Mar 26, 2013 at 10:10:02 pm

I bought a 240GB SSD just to dedicate caches to it to help speed up performance. (I've pointed all 3 AE caches to it) But, I've backed the "level" all the way down to 150GB, and I'm still getting the warning that it's set too high. What is it talking about? I'd expect to be able to use something like 235GB. What am I misunderstanding about the cache settings?

This -> "The Maximum Disk Cache Size setting specifies the number of gigabytes of hard disk space to use. In After Effects CS6, the default disk cache size is set to 10% of the volume's total size, up to 100 GB. In After Effects CS5.5, this amount is 20 GB, by default. Because of this, many more frames are eligible for disk caching than in previous versions" was taken from the following URL -

Thanks for the info. I'm a little concerned that this note suggests I may be having trouble with my new SSD.

"Note:
In After Effects CS5.5, and later, the application checks to make sure that you have 10 GB free above what is set in Preferences > Media & Disk Cache. After Effects warns you if there is not enough room for the disk cache."

This seems to suggest that 230GB would be a valid setting on a 240GB drive, doesn't it?

Is your 240GB SSD empty? How much free space is on the said drive?

Yeah, it's a brand new Mercury 6G 240GB, running off my 5th (3G) sata port on the motherboard of my MacPro 3,1 (2008).

1) ensure that the SSD works by copying stuff to/from the drive
2) set only the disk cache to use this drive
3) set the Conformed Media database and cache to another drive (your next fastest drive)

See if those help. If they don't, then try setting your cache to a smaller value - 150GB and then raise that until the hiccup returns. Then revert to the previously viable option.

Thanks Roland.

The SSD seems to be working, (copied about 1GB to it from a 7200 in about 10 sec)

After directing the other caches to another drive and emptying the cache, it looks like 212GB was my magic limit.

I then ("delete on move") re-directed the conformed caches back to the SSD, hoping that somehow they're not going to get in the way.

--Is this an unpublished ceiling limit, maybe?
--Anyone else have anything over 212GB?
--Or have anything to do with my running a 6G SSD on a 3G port?

Greg, 240GB is the pre-formatted (marketing info) size, no? 32GB is the per memory module size. After formatting, you're normally left with 224GB (7x32GB modules). Take away 10GB from 224 and you should have 214GB. Then account for rounding in all the calcs and it seems what you have, 212GB, is actually pretty decent.

That certainly makes sense, although I'll need to educate myself on the details of what you just said. I don't yet know what a memory module is nor why there are 7 of them.

I was just going off the "get info" capacity size of 239.71.

Google "SSD memory modules". Then look at Images and you'll see the individual memory chips that are embedded in an SSD. Lots of info in the 'read' links too if you want to delve deeper.

[Greg Neumayer] "After directing the other caches to another drive and emptying the cache, it looks like 212GB was my magic limit. "

I've got a 240 GB SSD in a PCIe slot in my HP Z800. I like to keep it under 200 GB so I have a little bit of room free for final-res proxies and pre-renders.

I love the disk cache feature, but sometimes I want manual control over what stays and what goes.

That's a good idea. I'm so tired of watching the Render info spend 90% of its time saying "Compressing and Writing".
